Discuss some of the problems NATs create for IPsec security. (See [Phifer 2000]). Can we solve these problems by using IPv6? Why deployment of IPv6 has been slow to date. What is needed to accelerate its deployment?
Name several multicast applications. Which of these applications are well-suited for the minimalist Internet multicast service model? Why? Which applications are not particularly well-suited for this service model?
Advantages and Disadvantages of Subnets
What are some disadvantages of subnets?
Supposed two TCP connections are present over some bottleneck link of rate R bps. Both connections have a huge file to send (in the same direction over the bottleneck link). The transmissions of the files start at the same time. What is the transmission rate that TCP would like to give to each of the connections?
I personally think the deployment of IPv6 has been slow because the Internet is still using IPv4. Until the whole scope of Internet users are forced to change to IPv6 there will be no acceleration of its deployment. The old saying comes into the forum; why stop using something that you know works and you are happy with?
Those applications that do not require a high level of reliability for operations can use the Minimalist Internet Multicast service model, like streaming of continues data in the forms of audio or video, however applications that need reliability like real time applications they would be best suited utilizing the unicast service ...continues
Today we have a big problem with advertising companies which are making profiles of people by collecting their information. With IPv6, this task would be much easier because if they found the user's identity of a specific IP address, then they would use the IP address to collect the information easier. Imagine if they know the I ...continues
Djkstra’s shortest path algorithm
Consider the following network. a) With the indicated link costs, use Djkstra’s shortest path algorithm to compute the shortest path from E to all network nodes. Show how the algorithm works by computing a table. b) Eliminate node A, and redo the problem starting from node B.
How to identify software, hardware and network problem.
Describe how to identify software, hardware, and network problems.
Many of the functions of an adapter can be performed in software that runs on the node’s CPU. What are advantages and disadvantages of moving this functionality from the adapter to the node?
